Phantasmagoria Canto Iii ( Scarmoges )
"AND did you really walk," said I,
"On such a wretched night?
I always fancied Ghosts could fly -
If not exactly in the sky,
Yet at a fairish height."
"It's very well," said he, "for Kings
To soar above the earth:
But Phantoms often find that wings -
Like many other pleasant things -
Cost more than they are worth.
